ER

10-11 PM · NBC · Returns Sept. 27

A 14-year-old medical show in a Grey’s Anatomy world, ER needs help — stat! ER exec producer David Zabel says Goran Visnjic will return for a bunch of episodes, as will Noah Wyle for four. And Stanley Tucci, the series’ go-to guy now for a grump fix, will be back, causing ”conflict and tension.” (On camera, not off — this ain’t Criminal Minds, folks.)
